Bratwurst are grilled until browned and juicy alongside marinated red onions tossed in olive oil, balsamic vinegar, thyme, salt, and pepper. As they cook, the onions soften and caramelize, adding a sweet, tangy contrast. Served in rolls and topped with the glazed onions and mustard, this dish delivers a bold balance of smoky, savory, and slightly sweet flavors—perfect for grilling.
